NXP Semiconductors MC7448HX1400ND

Overview

MC7448HX1400ND from Freescale Semiconductor is a PowerPC™-compliant RISC microprocessor built on Power Architecture™ technology, operating at 1400 MHz with a core supply voltage of 1.15 V ± 50 mV and junction temperature range of 0 to 105°C. It implements the PowerPC instruction set architecture version 1.0 and targets high-performance embedded computing applications such as network infrastructure control planes and telecom baseband processing.

For engineers reviewing the MC7448HX1400ND datasheet, MC7448HX1400ND pinout, MC7448HX1400ND application, or MC7448HX1400ND equivalent, key selection criteria include verified 1400 MHz full-power operation at 1.15 V, thermal power consumption of 13.7 W at 105°C, support for Dynamic Frequency Switching (DFS), and HCTE BGA package compatibility with MPC7448 hardware specifications.

Technical Context

The MC7448HX1400ND implements a superscalar, seven-stage pipeline PowerPC core with dual integer units, floating-point unit, and 1 MB on-die L2 cache. Its PLL supports VCO frequencies up to 1400 MHz and enables DFS modes (divide-by-2 and divide-by-4) for dynamic power management.

Power delivery requires strict sequencing: core (VDD), I/O (OVDD), and PLL (AVDD) supplies must follow defined ramp-up order per Section 9.2 of the MPC7448 Hardware Specifications. The device operates exclusively in HCTE BGA packaging with 360-ball layout and 1.0 mm pitch, requiring controlled-impedance PCB routing for DDR2 memory interface and 667 MHz system bus timing compliance.

Key Specifications

Pinout & Package

MC7448HX1400ND uses a 360-ball HCTE BGA package with 1.0 mm ball pitch and standard PowerPC-compatible pin assignment. Ball map follows MPC7448 Hardware Specifications Rev. 3+ with dedicated VDD, OVDD, AVDD, and ground balls distributed across the array for low-impedance power delivery.

FAQ

What is the confirmed core supply voltage specification for MC7448HX1400ND?

The MC7448HX1400ND requires a nominal core supply voltage of 1.15 V ± 50 mV, effective for all units with date code 0613 and later. This specification supersedes the 1.1 V ± 50 mV requirement for earlier 1400 MHz variants and is validated in Table 4 of MPC7448ECS01AD Rev. 6. The MC7448HX1400ND must not be operated at 1.1 V in production systems.

Does MC7448HX1400ND support Dynamic Frequency Switching (DFS)?

Yes, the MC7448HX1400ND supports DFS with core frequency ranges of 250–700 MHz when enabled, as specified in Table 8 of the hardware addendum. This feature allows runtime power reduction while maintaining architectural compatibility, and the MC7448HX1400ND implements the same DFS control registers and exception handling as other MPC7448 family members.

What package type does MC7448HX1400ND use, and how does it differ from VS/VU variants?

The MC7448HX1400ND uses the HCTE BGA package (360-ball, 1.0 mm pitch), distinct from the RoHS-compliant LGA (VS) and RoHS BGA (VU) variants. The HCTE variant features enhanced thermal dissipation via integrated heat spreader and is optimized for high-reliability telecom chassis mounting, whereas VS/VU variants prioritize environmental compliance over thermal performance.

What is the maximum thermal power consumption of MC7448HX1400ND at 105°C?

The MC7448HX1400ND exhibits 13.7 W typical thermal power consumption at 105°C junction temperature in Full-Power Mode, as measured per Dhrystone 2.1 benchmark at nominal 1.15 V supply. This value is documented in Table 7 of MPC7448ECS01AD Rev. 6 and forms the basis for heatsink selection in enclosed systems.

Is MC7448HX1400ND pin-compatible with other MPC7448 speed grades?

Yes, the MC7448HX1400ND shares identical pinout, ball map, and electrical interface definitions with all other MPC7448 HX-series variants (e.g., MC7448HX1250ND, MC7448HX1000ND), as confirmed in Section 9.1 of the MPC7448 Hardware Specifications. This enables drop-in replacement within the same HX package family without PCB redesign.
